We were able to visit George for a few minutes yesterday and he is doing very well. He was so excited to see us that he practically wagged himself sideways. He looks good and the vet says that he is healing well. He will stay at the clinic during our vacation and should be in good shape to come home and resume chasing Gracie when we return. Thank you all for your concern. It wasn't an easy decision but I think it was the right one.
